Optimized butyl butyrate synthesis catalyzed by Thermomyces lanuginosus lipase.

Biotechnol. Prog. 29(6) , 1416-21, (2013)

Butyl butyrate is an ester present in pineapple flavor, which is very important for the food and beverages industries. In this work, the optimization of the reaction of butyl butyrate synthesis catalyzed by the immobilized lipase Lipozyme TL-IM was performed....

Screening of food grade lipases to be used in esterification and interesterification reactions of industrial interest.

Appl. Biochem. Biotechnol. 160 , 1146-1156, (2010)

Seven food grade commercially available lipases were immobilized by covalent binding on polysiloxane-polyvinyl alcohol (POS-PVA) hybrid composite and screened to mediate reactions of industrial interest. The synthesis of butyl butyrate and the interesterifica...

Rate coefficients for reactions of OH and Cl with esters.

ChemPhysChem 11(18) , 4097-102, (2010)

Rate coefficients for the gas-phase reactions of OH radicals with n-propyl butyrate (k(1)), n-butyl propionate (k(2)) and n-butyl butyrate (k(3)) are measured by both absolute and relative methods. The kinetics data obtained over the temperature range 273-372...

Simultaneous Clostridial fermentation, lipase-catalyzed esterification, and ester extraction to enrich diesel with butyl butyrate.

Biotechnol. Bioeng. 110(1) , 137-42, (2013)

The recovery of 1-butanol from fermentation broth is energy-intensive since typical concentrations in fermentation broth are below 20 g L(-1). To prevent butanol inhibition and high downstream processing costs, we aimed at producing butyl esters instead of 1-...

Evaluation of immobilized lipases on poly-hydroxybutyrate beads to catalyze biodiesel synthesis.

Int. J. Biol. Macromol. 50(3) , 503-11, (2012)

Five microbial lipase preparations from several sources were immobilized by hydrophobic adsorption on small or large poly-hydroxybutyrate (PHB) beads and the effect of the support particle size on the biocatalyst activity was assessed in the hydrolysis of oli...

A new method for wide frequency range dynamic olfactory stimulation and characterization.

Chem. Senses 32(7) , 681-8, (2007)

Sensory receptors often receive strongly dynamic, or time varying, inputs in their natural environments. Characterizing their dynamic properties requires control and measurement of the stimulus over a frequency range that equals or exceeds the receptor respon...

Poly(styrene-divinylbenzene) beads surface functionalized with di-block polymer grafting and multi-modal ligand attachment: performance of reversibly immobilized lipase in ester synthesis.

Bioprocess Biosyst. Eng. 34(6) , 735-46, (2011)

Fibrous poly(styrene-b-glycidylmethacrylate) brushes were grafted on poly(styrene-divinylbenzene) (P(S-DVB)) beads using surface-initiated atom transfer radical polymerization. Tetraethyldiethylenetriamine (TEDETA) ligand was incorporated on P(GMA) block. The...

Strategies for enzymatic esterification in organic solvents: comparison of microaqueous, biphasic, and micellar systems.

Enzyme Microb. Technol. 14(10) , 791-7, (1992)

The kinetics of butyl butyrate synthesis by a lipase from Mucor miehei in different types of organic media were investigated. The three systems studied were a microaqueous medium containing enzyme in suspension in hexane, a water-hexane two-phase system, and ...

Lipase-catalyzed synthesis of butyl butyrate by alcoholysis in an integrated liquid-vapor system.

Biotechnol. Prog. 19(3) , 750-4, (2003)

This paper reports experimental work pertaining to alcoholysis between butanol and ethyl butanoate, catalyzed by an immobilized lipase in a liquid-vapor system where chemical reaction and physical separation are simultaneously carried out. The processing setu...

Immobilization of Candida antarctica lipase B by adsorption to green coconut fiber.

Appl. Biochem. Biotechnol. 146(1-3) , 173-87, (2008)

An agroindustrial residue, green coconut fiber, was evaluated as support for immobilization of Candida antarctica type B (CALB) lipase by physical adsorption. The influence of several parameters, such as contact time, amount of enzyme offered to immobilizatio...
